Technology partners who provide API integration services to multiple merchants are required to send their partner registration ID and software name in the User-Agent HTTP request header of all API requests.
Merchants who integrate directly with DHLeC are not assigned a registration ID and do not need to send a custom User-Agent HTTP request header.
The registration ID is a 6-character alphanumeric value assigned by DHL eCommerce. The software name is chosen by the technology partner and can be any value, up to a length of 50 characters.
Within the User-Agent HTTP request header, the two elements should be separated by a single space character:
User-Agent:[REGISTRATION_ID] [SOFTWARE_NAME]
Example:
User-Agent: ABC123 ShipMaster Pro
If you have any questions about the technology partner identification scheme, please reach out to your solutions partner manager.
It is possible that your security team may need to whitelist DHL eCommerce IP addresses, so that your systems are able to communicate with the DHL eCommerce API. If this is the case, you can reference the list of DHL eCommerce IP addresses below.

Updated October 8, 2021
Identifiers
packageId
Customer-provided package ID, also known as the CCN (customer confirmation number) or the GM number.
Example: GM60511234500000001
dhlPackageId
DHL-generated package ID. This value is generated differently for domestic and international packages (domestic: mail identifier; international: TMUID).
Example: 3387191106122423
trackingId
Last-mile carrier package ID. For international shipments, this ID is only available after the package has been shipped. For domestic shipments, this ID contains the full USPS IMpb number and is always available. If the package is overlabeled for any reason, this field contains the latest carrier package ID.
Example: 420071149361269903500011492028
deliveryConfirmationNumber
For domestic shipments, this is the USPS tracking number, which is part of the IMpb number and is also sometimes referred to as the PIC (package identification code). If the package is overlabeled for any reason, this field contains the latest USPS tracking number. For international shipments, this field contains the last-mile carrier package ID (same value as the trackingId field) and is only available after the package has been shipped.
Example: 9361269903500011492028
overlabeledDspNumber
For domestic shipments which have been overlabeled, this is the original USPS tracking number. The USPS tracking number is part of the IMpb number and is also sometimes referred to as the PIC (package identification code). For international shipments and non-overlabeled domestic shipments, this field is unused.
Example: 9261269903500013618305
intelligentMailBarcode
For domestic flats shipments, this is the USPS IMb number. If the package is overlabeled for any reason, this field contains the latest IMb number. For international shipments and non-flats domestic shipments, this field is unused.
Example: 0031043534391627906195625053434
overlabeledIntelligentMailBarcode
For domestic flats shipments which have been overlabeled, this is the original USPS IMb number. For international shipments and non-overlabeled / non-flats domestic shipments, this field is unused.
Example: 0031043534391640211895625057522
manifestId
Unique identifier for each manifest created in the DHL system. This is returned in the Get Manifest API where each manifest will have the manifestId as the unique reference. This will also be barcoded and printed on the Driver Summary Manifest (DSM).
Example: 532903701308165834461
requestId
Unique identifier for each manifest request that was submitted to the DHL system. This is used to download and print the manifests later using the Get Manifest API. A single requestId can result in multiple manifestId when there's more than one manifest being generated for the request.
Example: bae87627-3566-4670-b8d2-fe90bfed75a9
Conventions
Package
The smallest unit in shipping is an Article / Piece / Item / Package / Parcel. These words are often used interchangeably. For the purposes of this API documentation, we use the term Package everywhere.
Shipment
The next higher unit is called a Shipment. This means one or more Packages going to the same destination (end consumer). A group of Packages is called a Shipment.
All of our shipping products support only 1 package per shipment hence we use the term Package and Shipment sometimes interchangeably.
Manifest
Also called a BOL / Bill of Lading / Consignment note / handover document / DSM / closeout document / DMF, a Manifest is a set of packages grouped by some common characteristic, such as those bound to the same distribution center after pickup, same shipping product, shipping class (domestic or international) etc. For example, all Domestic packages bound to a single distribution center will go into a first manifest, X-border packages bound to a single distribution center will go into a second manifest, Domestic packages bound to another distribution center will go into a third manifest etc. Sometimes, a new manifest can be created also because of technical limitations on maximum number of packages that can be successfully processed in a single manifest request.
Order
When one or more Manifests are picked up from the same origin (pickup location), it's called an Order. An Order can contain Domestic and X-border packages and can go to one or more Distribution facilities. It is simply a pickup load.
Container
A Container is a physical unit to carry a group of Packages, Manifests or Orders. A Container should contain at least one Package. A Container can contain less than 1 manifest, 1 manifest or more than 1 manifest. A Container can contain less than 1 Order or 1 order.
De minimis
A customs duty de minimis value (or VAT de minimis value) is the minimum threshold which an imported good's value must exceed in order to incur customs (or VAT) charges.
Weights
Weights are subject to applicable corrections when package(s) are weighed/measured at DHL eCommerce facilities.
Billable Weight
Weight that will be used for calculating fees and charges. This will be the Actual Weight, rounded up to the nearest oz for Parcel products and nearest lb for Parcel Plus products, unless the following three criteria are met:
Actual weight greater than or equal to 1 lb
Volume (L*W*H) is greater than 1 cubic foot
Volumetric (Dimensional) weight (L*W*H*(DiscountFactor, if applicable)/166) is greater than Actual weight
Then the Dimensional Weight will be used.
Actual Weight
Weight provided by the client in Label API and/or Product Finder API request.
Dimensional Weight (a.k.a.: Volumetric weight)
Weight calculated using dimensions provided in the dimensions object of the Label API and Product Finder API request. It is calculated by multiplying Length x Width x Height x (Discount Factor based on package Type, if applicable) / Dim Factor.
